Parts Energized When the Main
Power Switch is OFF
The following components are powered regardless of
whether the SW1 (main power switch) is ON or OFF,
provided that the power cord remains plugged in.
a.
CBR1 and CBR2 (circuit breakers)
The circuit breakers serve to protect against damage
from short circuit. If current exceeds 8A, the circuit
breaker(s) will go OFF, cutting the power to the
system.
b. DCPS (DC power supply)
Supplies power to each unit and also controls the
ON/OFF state of the fixing lamp.
